We run silver can (mabuchi, Johnson) motors as per the house rules. The fastest Mini Class cars are about 2-3 laps off the pace of the fastest sedan type cars, about the C-main in most cases. It just depends on the layout of the track that gets changed from time to time. We tried ROAR stock motors for a few rounds and the cars got quicker as you would expect, some of the best times would have been in the top of the B and bottom of the A. We went back to the silver can motors though because the tire wear got to be a bit much. Besides the mini class isnt supposed to outrun the sedans is it?
